Guidelines For Digital Plat Submittal


The guidelines for submitting digital plat include:

  • Alta is on HARN, the rest of the County is on NAD83
  • An ASCII point file is not required when a DXF or DWG file is provided
  • AutoCAD 2004 (and newer) format files are NOT being accepted. Please save to an older versions
  • Bearings, distances, certificates, notes, and other annotations are not required
  • Digital plats are required even when state plane coordinate ties are not
  • Do  not put a plat on state plane coordinates unless you really surveyed  the control in (do not use the GIS to get your coordinates)
  • Drawing files should be on state plane coordinates (rotated to grid,  scaled to ellipsoid), rather than on a local surface datum with ties to  state plane control annotated
  • Drawings should be two dimensional, not 3D (all Z values should be 0)
  • Files may be emailed to or provided on floppy disk
  • Line trimming at ends to create hollow point symbols should be avoided. This is a bad practice for any digital data exchange
  • Lot numbers and street names are required
  • Only access easements are used in the GIS. If you include other types of easements (utility, snow storage, view corridor, etc.) please identify them as such
